Y 'i @ameri-ed with it by v Y v D vertical cylinez" Y, awa fa be suisorted by brac et F from SEiizrd T cylinder E has in it bore E 'fffsle smaller diameter ih riarfi' Qi the Ghamber DB of said stationary no ryider, so that the crass areas nf said bore and @flamber may be in preperg of @ne 0f the former to fifty, one hundred, or live hun- --lred like diameters in the latter or in :my other suitable proportion preferred or that may be found to be advantageous. Pistonhead D2 ma be made ot any suitable nietnl or allo or ot ier suitable substzmee, so as to nice yfit thewallsof theehember D" und vethe allowed to freely move in the said eyiinder Without leaking. My preferred form of ronstruetion of the piston-head D2 is shown in Fig. 4, in which is em iloyed the lower section d and upper section and thin peeking-disk d', of a suitable liable substance, preferably rubber, d and being of diameter slightly less than the inside diameter of the walls of the c linder D, while that of the packingdisk is of suitable diameter for making a water-ti ht joint adapted to prevent escape of liqui from the said rhamber under small pressure. These two sections d and d are preferably secured together by means of inding-screws d passing up through the lower section d and screwing into the u iper section and adapted to be tightened or oosened from below, so as to allow the said binding-screws to be operated in either diret-tion for tightening or loosening the same, as may be required for slightly expanding the outer margin of the rubber parking-disk d2 or nllowingit to contract, as may be found to be neeessary to produce a water-tight joint without excessive pressure of the rubber on the wall of the e linder. From the lower side of seetion d o this piston-head is projected the hollow stem d4, which ronneets `the piston-rod E1 with the rider-piece G, whiehrides on the outer or free end of the lever C. Between this rider-mecc G and lever C is preferably arranged roller G', whieh is designed to relieve the said rider of liability of binding on said lever.

The smaller eylinder E eommunieetes with tho lalljghr cylinder l) and has working in its bore i' piston-head E, suitably parked, (preferably same as piston-head l),) so as to have a. water-tight joint between it und the ('tylinder-Walls. This piston-heard is conneried with the lower end of the piston-rod IC and extends upward through the bore E' und out from the same to between rollers ll ll. Roller H revolves on pintle Il., whit-.h may be fixed stationary in the heard lt" of braeket F, und rollerrll revolves with pintle h', whit'h is ireferably revolved in an adjustable, bloek l, suitably su )ported und guided in the Said head F and at apted to be relatively moved toward and from the cylinder IC, so as to carry roller ll in a. correspondingr direetion. Any suitable means muy be employed for moving said block, yet l prel'er to em iloy adjusting-screw Il, l'or that purpose. ily these described devires the sind two rollers Il und ll muy be made to have a suitable, pressure on the opposite sides ol the piston-rod E, so that they may be revolved by the notion of the latter when moved verlirsllly in either dirertion. (me ol these rollers. prel'ernldiy the ndjustuhle roller ll', eurries the index-hand l, mounted on un outer end ol' the revolving plllti fl'l Ui siltl IUlhl lli, su is lo lu nnmml to registration with the thirhness-indit-titing points on the seule lan't-ordingl \4 ns t he thinkness of the said web may, through the .st-wml mechanisms employed between the verlitnl moving revolving rylindet and 'suid revolving wheel, be rispeetivel \r moved.
